The London Underground

On July 7, 2005, one day after London won the right to host the 2012 Olympics, four suicide bombers killed 52 people on London’s public transport system. With those bombings in mind, officials have beefed up their security presence on the London Underground. They haven’t, however, revealed precisely how. As one official said at a security briefing in June: “We hope that you will not notice a significant additional security presence, but I can assure you there is significant effort being undertaken.” That likely includes more surveillance and, as some Londoners have already noticed, more policemen in and around Tube stations.
